in order to help you, I need more information. If I understand you  
correctly, you do not want to set the environment variable SDLDIR.  
Instead, you expect the FindSDL module to find SDL without that  
information. Is that correct?
Please give some more information about your installation. In which  
path exactly is SDL located (where is "SDL.h", where is "libSDL.a" or  
"libSDL.so")?

Kind regards
Benjamin
